210.8(B)(2)

[anbm]

210.8(B)(2) requires 50A or less, single phase, 150V to ground or less outlets located in non dwelling unit kitchen to have ground fault protection.
Also, by other code, if the outlet serving cooking equipment located under kitchen hood it must be fed by a shunt-trip breaker circuit. Can a breaker have combined of both features, i.e. shunt trip and ground fault protection to meet this?

I'm guessing you may have hard time finding both GFCI and shunt trip on most miniature style breakers that would be commonly used for this.

Best thing is likely to supply a panel with the under hood items, put GFCI breakers as needed in it and then use a shunt trip breaker for the feeder to that panel.

Or vice versa right?

Or vice versa right?

GFCI protecting the entire panel via its feeder might be more prone to nuisance tripping.

Using shunt-trip breakers is not the only way to shut down under-hood equipment.

You can use contactors held closed, and/or GFCI receptacles or outboard GFCI devices.

Most common way we (I build a lot of restaurants) accomplish this is via a shunt trip breaker feeding an entire panelboard dedicated to under-hood equipment.

There are no miniature breakers that feature GFCI and shunt modules, but I believe you can get an i-line with both.

What's the big deal ... have a panel dedicated to kitchen equipment with a shut-down breaker.

And it likely cost as much as other arrangements plus maybe at least a 6-12 month lead time the way things been lately.

Yes, if you have 3 circuits with leakage of 2mA, 3mA and 2mA, you have enough overall leakage to trip the feeder GFCI, but put same three circuits on individual GFCI's and you are below trip threshold on each circuit.
